An electrographic printer/copier capable of producing color prints is disclosed. The color printer/copier comprises a housing, a source of paper and an output for the paper after it is imprinted, a photoconductive member, and a developer unit containing toners of multiple colors. On successive revolutions of the photoconductive member, the developer unit applies a different colored toner to the photoconductive member. After each revolution of the photoconductive belt, the image developed in a particular color is transferred to and retained on a transfer belt. When all of the different colored images have been transferred to the transfer belt, a sheet of paper is brought into contact with the transfer belt and the fully developed color image is transferred to the sheet of paper. In a preferred embodiment, the photoconductive member is a vertically aligned photoconductive belt. The transfer belt is horizontally aligned and located above the photoconductive belt. The sheet of paper travels along a substantially planar paper path located either above or below the transfer belt and the fully developed color image is transferred to the sheet of paper. |
